Objective: The purpose of this study was to explore the structural analysis of the relationships among principals and fellow teacher's emotional support, teacher's active motivation for choosing the teaching profession, self-leadership, and child care efficacy and commitment. Methods: Data were collected from 465 child care teachers and analyzed by means of structural equational modeling(SEM). Results: First, principals and fellow teacher' emotional support was found to have a direct effect on teacher's child care commitment, as well as an indirect effect through teacher's self-leadership. Second, teacher's active motivation for choosing the teaching profession was found to have a direct effect on teacher's child care commitment, as well as an indirect effect through self-leadership and child care efficacy. Third, teacher's self-leadership was found to have a direct effect on teacher's child care commitment, as well as an indirect effect through child care efficacy. Fourth, teacher's child care efficacy was to found have a direct effect on teacher's child care commitment. Conclusion: These results suggest the need for a great deal of utility to improve teacher's child care commitment.

Industrial manipulators have been mostly used in large companies such as automakers and electronics companies. In recent years, however, demands for industrial manipulators from small and medium-sized enterprises are on the increase because of shortage of manpower and high wages. Since these companies cannot hire robot engineers for operation and programming of a robot, intuitive teaching and playback techniques of a robot manipulator should replace the robot programming which requires substantial knowledge of a robot. This paper proposes an intuitive teaching and playback algorithm used in assembly tasks. An operator can directly teach the robot by grasping the end-effector and moving it to the desired point in the teaching phase. The 6 axis force/torque sensor attached to the manipulator end-effector is used to sense the human intention in teaching the robot. After this teaching phase, a robot can track the target position or trajectory accurately in the playback phase. When the robot contacts the environment during the teaching and playback phases, impedance control is conducted to make the contact task stable. Peg-in-hole experiments are selected to validate the proposed algorithm since this task can describe the important features of various assembly tasks which require both accurate position and force control. It is shown that the proposed teaching and playback algorithm provides high positioning accuracy and stable contact tasks.

The goal of this research is to prove the efficiency of direct instruction by developing and applying an ICT teaching and learning course for physical education based on a direct instruction model. The curriculum for physical education requires the instructors example and feedback, and sometimes classes may be difficult to conduct due to reasons such as weather conditions. Also, in actual learning, the application of a learning model is inadequate. In these cases, using an ICT teaching and learning course, experts can show examples instead. The learners are provided with individual and suitable feedback and can make it practical for them by slowing down motions, sectional motion learning, and repetitive learning. It can also enhance the sharing of the instructors teaching and learning methods. Therefore, this research recomposed the commonly used direct teaching and learning methods in physical education in order to make it suitable for ICT utilized lessons. It was recomposed in a procedural model and each level was explicated, and in order to materialize this, an ICT teaching and learning course was developed. This was then applied to a Fifth grade class, and its learning effects were analyzed.

The purpose of this study was to examine the effect of socioeconomic status and the children's sex on mothers'teaching strategies and their children's responses during a cooperative problem-solving task. The subjects were 15 higher SES mothers and their 5-years-old children dyads. The mothers' teaching strategies and their children's responses were videotaped during a cooperative problem solving task and analyze using a scheme developed by Kermani and Brenner. The results of this study were as follows. First, the mothers with higher SES were more likely to promote 'independence' and less likely to 'verbal prompt'direct performance' than the mothers with lower SES. Second, the children from higher SES families were more likely to refuse their mothers' assistance. Third, the mothers of boys were more likely to use the 'direct teaching'and 'modify'strategies and less likely to use 'independence promoting'strategy than the mothers of girls. Finally, girls were more likely than boys to ask questions for assistance or assurance.

Objective: This study investigated the relationship between preschool teachers' creativity, teaching efficacy, and creativity-fostering teaching and examined the mediating effect of teaching efficacy. Methods: A total of 202 preschool teachers participated in this study. The Creative Behavior Inventory (CBI), Teaching Efficacy Scale, and the Creativity-Fostering Teacher Behavior Index (CFTI) were used for the survey. A hypothesized model and alternative model were tested using structural equation modeling. Collected data were analyzed using 18.0 PSAW and AMOS. Results: The results showed that preschool teachers' creativity was positively associated with their teaching efficacy and creativity fostering teaching. Preschool teacher's teaching efficacy positively related to their creativity fostering teaching. Preschool teachers' creativity had a significant positive direct effect on creativity-fostering teaching and also an indirect effect on creativity-fostering teaching via teaching efficacy. Conclusion/Implications: Implications to foster creativity in preschool and kindergarten are discussed, highlighting the necessity for teacher education to promote teaching efficacy as well as teacher's creativity and creativity-related activities.

The purpose of this study is to investigate a structural relationship among elementary students' self-determinant learning motivation, teaching-presence and learning outcomes (learning satisfaction, persistence) in blended learning environment. Participants were 5th and 6th grade students who enrolled in a mathematics learning service. The results showed that self-determinant learning motivation had direct effect on teaching presence, learning satisfaction and learning persistence. Teaching Presence had an direct effect on learning satisfaction and learning satisfaction had an direct effect on learning persistence. Based on the results, proper strategies were recommended to facilitate self-determinant learning motivation and teaching presence before and during learning since they play critical roles for the success of elementary students learning outcomes in a blended learning environment.

To improve the elementary student's ability to classify the data and obtain the information from the data through graphics, it is necessary to use the teaching and learning material which encourage the student to study with interest and is adjacent to the student's environment. In this thesis. several materials to satisfy the condition is proposed together with some remarks to direct the teaching. These materials is recommended to use for the maturity learning and teaching in grade 6.

This study examined how pre-service elementary teachers' perceptions regarding the learning environment (learning focus/ability-meritocracy/cooperative climate) and achievement goals (mastery/performance-approach/performance-avoidance) in science education courses jointly contributed to their science teaching efficacy beliefs (personal science teaching efficacy belief/science teaching outcome expectancy). A path analysis supported a causal model in which the perception of the learning focus influenced the mastery goal, which in turn influenced the personal science teaching efficacy belief and science teaching outcome expectancy. The perception of learning focus also had a direct effect on science teaching outcome expectancy. The perception of ability-meritocracy influenced personal science teaching efficacy belief via the performance-approach (positively) or, conversely, the performance-avoidance goal (negatively). No link .was deduced from the perception of cooperative climate. The educational implications of these findings were also discussed.
